X-ray spectroscopy of fluorescence radiation channeling in μ-capillary holed glass plates. Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms Volume 309, 2013, Pages 240-243

Capillary optics is a fundamental X-ray technology capable of generating a high flux density with sub lm spot size. The physical basis of capillary optics refers to the mechanism of the total external reflection of X-rays although experimental data about the transport of the radiation inside such kind of structures are really limited. We present here the data of reflection and transmission soft X-ray synchrotron radiation experiments performed with different types of microchannel plates. In particular, we discuss the presence of fine structures in the XANES spectra at the energy of the Si L-edges detected at the exit of micro-capillary structures under the condition of the total X-ray reflection. © 2013 Elsevier B.V.
